Abstract (en)
It is a transmitter of brief data by radio waves, connected to a sensor located in the tank, reservoir or deposit that allows the user to know the level of liquid or gas in these tanks. It transmits the information to its corresponding receiver through a determined channel (fig.4), which allows the use of other systems in the same place. It is powered by a battery (fig.2) so that the transmitter can reduce its electric consumption. It only effectuates the transmission when necessary (fig.2) and periodically (fig.3) to prevent a loss of synchronisation with the receiver. The durability and reliability of the system is thus increased. The receiver is connected to a source of electric current (fig. 14), displaying the information in a simple and convenient way from the user's own home (fig 13-1) and at a distance that is adequate to the necessities of the installation. Its simplicity of installation, use and maintenance make this tool a product of low consumption and fabrication costs. <IMAGE> <IMAGE>
